The designer sums porch legs (width × length each), which undercounts a wraparound because the shared corner belongs to both legs. The builder can confirm a higher figure per job; that number then wins over the leg-sum everywhere, including in labour.
Also called: wraparound porch · porch square footage wrong · corner not counted
- 1The auto leg-sum is shown with the option to confirm a different number.
- 2A confirmed override is persisted per job and baked into the estimate snapshot on send.
- 3Setting it immediately recomputes the labour calculator's under-roof square footage.
- 4Absent an override, the auto leg-sum is used.
A wraparound porch's shared corner belongs to both legs, so adding the legs up undercounts it — one job summed to 240 square feet where the real covered area was 340. That corner was on the roof and being framed, and it was priced at nothing. Raising the porch figure now feeds the labour calculator as well as the customer's porch line, because the porch total is part of the roof and labour has to see the same number the customer does.
- Shared porch corners framed at no charge because the leg-sum missed them
